Is it normal to have one bar on a new crown self-test kit
It is generally considered negative or invalid.
Result interpretation: only the C line is colored, representing a negative; while the C line and T line "two bars" are colored, representing a positive; only the T line is colored or colorless, representing an invalid result.
Antigen testing is an important complement to nucleic acid testing. Antigen testing does not require special techniques and produces rapid results in 15-20 minutes.
Because of its convenience, antigen testing can be done continuously for three consecutive days, and the sensitivity and specificity of the combined results will not be lower than that of nucleic acid testing, which is done only once in three days.
The correlation between patients identified through antigen testing and infectiousness is much stronger, and some infections can be detected quickly and managed as early as possible.
How to use the new crown self-test kit
The new crown antigen rapid test kit of Boto Bio is in English from the packaging, and each large box comes with 5 test kits and supporting tools.
Specifically, it includes a nasal swab (similar to the sampling stick used in hospitals for nucleic acid testing), a sampling tube with liquid inside, and a sealed test card.
The instructions that came with the kit were also in English, but there were diagrams, and you could scan the QR code on the instructions to see a video demonstration of how to use it. An electronic copy of the manual was later obtained in Chinese.
A hands-on experience followed. Since the nasal swabs only need to be placed into the nasal cavity on both sides at 1 cm?1.5 cm to rotate, the discomfort was significantly less compared to the hospital nasal swabs for the new coronary nucleic acid test, and it was also easy to maneuver.
The nasal swab is then rotated into the sampling tube containing the liquid, which is then dripped into the holes of the test card.
The results were obtained after 10 minutes of waiting, and only a dark red band was evident in position C. The result was "negative" and passed.
How much does the new crown self-test kit cost
Regarding the price of the antigen test, Huang Ailong, president of Chongqing Medical University, analyzed that the reasonable range of the factory price of about 1 person, 5 yuan, 2 people 8-10 yuan, the terminal selling price of not more than 20 yuan / person. But he also said the same: "For the time being, the cost of antigen detection by the scale of production, the source of raw materials and other factors, the current cost increase is large, the key raw materials in short supply."
According to the "program", primary medical institutions equipped with nucleic acid testing reagents into the centralized bidding and procurement, can be through the provincial centralized recruitment and procurement, and constantly reduce the price of testing reagents, reduce the cost burden of testing reagents.
And the testing reagents required by the isolation and observation personnel, do not need to pay out of pocket. According to the pilot program, this part of the reagents by the organization of the management of the isolation observation (such as communities, villages, towns, isolation sites, etc.) is responsible for antigen detection reagents procurement, distribution, management and other related work.
